Scented Crinum xpowellii ??

I am not sure how hardy C. jagus is but it has certainly been hardy and
healthy in zone 8
I have one that has been ID'ed as a variation pf C. jagus called C.
giganteum.
I was lucky enough to live in Naples, FL where Henry Nehrling (who brought
giganteum to the US) retired, I lived a few blocks from his Carribean
Gardens. This plant came from an old garden in Naples as a gift from a
friend.
The scent is an amazingly intoxicating vanilla/honey that still brings a
smile to my face every time it blooms.
